What is causing this Error?

The currently assigned GUID (Global Unique ID) does not match the currently registered GUID on the Shift4 data center. This is typically due to one of the following:

• Hardware changes have occurred on the PC. 
  • (IE: The Motherboard\Network Card was swapped out, or the Hard Drive was cloned.)
• Two or more UTG's are fighting for the same 'slot' assignment for the Shift4 datacenter.

See, UTG Slots Declassified for more information on how slots work.

How do I resolve this Error?

You will need to determine the following:

• Did changes occur to the PC hardware the UTG is installed on? 
  • If yes a simple slot reset can be performed to register the newly assigned GUID.

• Do they have another PC on the network that has a UTG installed on it?
  • If yes it's possible both PC's are assigned the same slot assignment and are fighting one another for connection. You will need to determine if the second UTG server is needed.
    • If the second server isn't needed the UTG software should be uninstalled from the unused PC. 
    • If they do have use for two UTG's you will need to assign a unused slot number for the second UTG and reset both slots.

Resetting a Slot [Gateway]

To request a slot reset is quite simple. You will be given access to a system called My Portal which can be accessed through www.shift4.com > Client Center > My Portal.

You will need to use your Windows Log-in Name and Password to access the slot reset systems. 

• Shift4/[WINDOWS USERNAME]
• [WINDOWS PASSWORD]

Once logged in you will have a section titled support. Under this option is the options to reset slots based on environment.

• Serial/Slot Activation – Production (LIVE)
• Serial/Slot Activation – Certify (TEST)

make the selection for the type of environment you are resetting the access for.

Enter in the serial number for the account that host the UTG and the Slot # you would like reset. You would then select an EOD from the list to send the reset notice to.

After hitting submit the page will provide a text box of the requested details at the top, this should be copied and pasted into the case for record keeping.

Once this is done the slot is reset automatically and you are ready to try connecting.
